ASTM A335 Grade P22 pipe shall be suitable for bending, flanging, and similar forming operations, and for fusion welding.

Each length of pipe shall be subjected to the hydrostatic test. Also, each pipe shall be examined by a non-destructive examination method in accordance to the required practices.

The range of ASTM A335 P22 pipe sizes that may be examined by each method shall be subjected to the limitations in the scope of the respective practice.

The different mechanical test requirements for pipes, namely, transverse or longitudinal tension test, flattening test, and hardness or bend test are presented.Both ends of each crate will indicate the order no., heat no., dimensions, weight and bundles or as requested.

Material & Manufacture

Pipe may be either hot finished or cold drawn with the finishing heat treatment noted below.

Heat Treatment

A / N+T
N+T / Q+T
N+T

Mechanical Tests Specified

Transverse or Longitudinal Tension Test and Flattening Test, Hardness Test, or Bend Test
For material heat treated in a batch-type furnace, tests shall be made on 5% of the pipe from each treated lot. For small lots, at least one pipe shall be tested.
For material heat treated by the continuous process, tests shall be made on a sufficient number of pipe to constitute 5% of the lot, but in no case less than 2 pipe.

Notes for Bend Test:

For pipe whose diameter exceeds NPS 25 and whose diameter to wall thickness ratio is 7.0 or less shall be subjected to the bend test instead of the flattening test.
Other pipe whose diameter equals or exceeds NPS 10 may be given the bend test in place of the flattening test subject to the approval of the purchaser.
The bend test specimens shall be bent at room temperature through 180 without cracking on the outside of the bent portion.

Quality Control

Whilst providing a quality, trusted service, we also place a high premium on quality craftsmanship. Our steel products are long-lasting, and always meet our clients exact specifications.

The purpose of this section is to display the general parameters and guidelines for the quality control of products manufactured on a day to day basis at the manufacturing facilities of Sunny Steel.

It is the intent of Sunny Steel to furnish products of the highest quality, using the best materials and workmanship available. All personnel involved in the quality control process, whether they are the location manager, or their designee, will conduct themselves in a professional manner, with the best interests of Sunny Steel Enterprise, and the customer in mind.

Testing:

The production and inspection technological process of our company is arranged according to production standards, and we also establishes professional inspection organization which takes charge of the quality inspection of all process from raw material into the company to the final product store up. Inspections including destructive testing and non-destructive testing.

Our range of steel pipe testing equipment is among the most expansive in the seamless tube manufacturing industry. This equipment is essential for testing both the chemical and physical properties of each seamless pipe and the material used to make it. It also allows us to detect hidden steel tube defects, ensuring the pipe quality. Listed below is our primary range of testing equipment currently in operation.
